Australia’s peak science agency, the CSIRO, has backed away from attributing a decade of drought in Tasmania to climate change, claiming ”the jury is still out” on the science.

The comments follow the issuing of a CSIRO report yesterday, revealing drought has cut water availability in northern Tasmania’s premier wine growing region by 24 per cent, with riverflows reaching record lows. One of the report’s co-authors, hydrologist David Post, told The Canberra Times there was ”no evidence” linking drought to climate change in eastern Australia, including the Murray-Darling Basin.

”At this stage, we’d prefer to say we’re talking about natural variability. The science is not sufficiently advanced to say it’s climate change, one way or the other. The jury is still out on that,” Dr Post said.

Australian Greens leader, Bob Brown has accused CSIRO of ”caving in to political pressure” to soften its stance on climate change in the lead-up to this year’s federal election.
